Max Planck Florida Institute for Neuroscience in Jupiter and its scientist Hyungbae Kwon have been awarded a $6.8 million grant — the largest in its eight-year history.

Kwon, scientific group leader at Max Planck Florida, has received a 2018 Director’s Pioneer Award from the National Institutes of Health for developing a new light-based technique that allows scientists to visualize and map out how emotions affect neurons. Neurons convey information like pain or hunger, which can affect how happy someone feels.

He is one of 10 scientists to receive the special grant this year, which is over five years, according to Max Planck, which announced the award Tuesday.
